VALVED COLLAPSIBLE TUBE.

Application filed April 5, 1920. Serial No. 871,227.

To cZZ whom it may concern:

Be it known that I, HERBERT L. FRIZELL, a citizen of the United States residing at Dorchester, in the county ofSuflolk and State of Massachusetts, have invented new and useful Improvements in Valved Collapsible Tubes, of which the following is a specification. 1

This invention relates to collapsible tube or like receptacles for containing and dispensing semi-liquid, or viscous fluid substances, such as tooth-paste, adhesives, shaving cream, paints and materials of like nature, thetube being made of a ductile or pliable metal or alloy, and adapted to be filled at one end and to have the end closed in the usual manner, and provided at the opposite end with a contracted neck having an outlet through which the fluid contents may be forced by external collapsing pressure exerted on the tube.

One object of the invention is to provide such a tube or container, of which the contracted neck containing the outlet is an integral part, with permanently associated valve means, in the form of a cap sur rounding the contracted neck, adapted to open and close the outlet. Another object is to provide an effective means for securing the cap to the neck of the tube, and still another object is to provide suitable stop means associated with the securing means for limiting the rotary movement of the A collapsible tubular container equipped with the preferred embodiment of my in vention, is illustrated in the accompanying drawings, which constitute. a part of this specification.

In the drawings,-

Figure 1 is an end view of a collapsible tube embodying the invention.

Figure 2 is a side view of the same.

Figure 3 is an end view of the tube, showing the shape of the aperture in the end wall of the neck.

Figure 4 is a longitudinal section through the neck of the tube, the valve cap being removed.

Figure 5 is a perspective view of the neck of the tube, showing the aperture in the top thereof.

Figure 6 is a perspective view of the valve cap.

Figure 7 is a sectional View similar to Figure 4, but showing the cap with securing rivet in place.

Figure 8 is. a perspective view of the rivet.

Figure 9 is a view similar to that shown in Figure 7, with the upper end of the securing rivet'headed over to secure the cap on the neck of the tube. i

The same reference characters indioatethe same parts in all of the figures.

In the drawings, 12 represents the body of an ordinary collapsible tube, and 18 represents the integral contracted tubular neck thereof, connected with the body 12 by a breast portion 14:. The neck is provided with a port 15, in its side wall, and with an end wall or head 16 containing an aperture 17. Said aperture, as shown in Figures 3 and 5, has a circular portion in the center of the end wall 16 and a sector shaped notch 19 extending outwardly therefrom. Mounted upon the neck is a cap or valve 20 having a tubular sleeve part fitting snugly about the neck, said sleeve having a port 21 therein adapted to be brought into coincidence with the port 15 in the neck, to form an outlet for the contents! of the tube or container. The upper end of the cap is closed by an end wall or head 22, in which there is a central aperture 23, shown in Figure 6, having a narrow notch 24 extending from one side thereof.

The cap is secured to the neck by means of a rivet 25, which is provided with a flange 26. contacting with the underside of the closed end or head of the neck, and a stem 27, which extends up through the central apertures in the ends of the neck and cap. The stem has formed thereon a lug 28, eX- tending radially therefrom and substantially filling the notch 24 in one of the end walls,

preferably the end wall 22 of the cap, as

here shown, whereby rotation of rivet 25 relative' to the cap 20 is prevented. The lug extends along the rivet body far enough to occupy the notches 19 and 24 of both of the neck and cap, and that portion of the lug which occupies the sector-shaped notch 19 in the head of the neck forms a stop which cooperates with the sides29 of the notch to limit the rotary movement of the cap. The sides 29 are spaced at such a distance apart, andv are located in such relation to the port 21 and the lug 28,that one of the sides 29 of the notch 19 will contact with the lug 28 when the ports 15 and 21 are in coincidence, and the other side of the notch willabut with the lug when the port 15 is closed. The -upper end of the rivet is peened down to form a head 30, thereby securing the cap to the neck. It is within my contemplation to reverse the relative positions of the notches 19 and 24, for the narrow notch may be made in the neck end wall 16 and the wide notch in the cap end wall 22, with equal effect.

The neck of the tube is very small in diameter, and in order that the rivet may be put in place when the parts are being assembled, it is formed with an extension 31 on its inner end adapted'to be set in a sultable holding tool. Such tool, carrying the rivet, is passed through the tube from the open end of the latter, and supports the rivet while the protruding end thereof is being headed over.

It will be noted from the above description that the rivet 25 serves the function of securing the cap 20 to the neck 13 of the tube, and the lug 28 projecting therefrom limits the rotary movement of the cap relative to the neck; while the flange 26 overlies the notch 19 and excludes therefrom the pasty contents of the tube, access of which to the notch would more or less prevent free rotation of the valve cap to the desired extent.

By the present invention 1 have provided a container of the collapsible tube type, having an integral contracted outlet neck, with an external permanently attached cap or valve, the attachment of which to the neck is effected through the agency of end walls on the neck and cap, respectively, and a pivot member engaged with said end walls. I have also furnished an efiicient and at the same time simple mode of effecting pivotal connection between two adjacent members, and a stop for limiting relative rotation of said members about the aXis of such pivot connection, by means of a lateral projection on the pivot occupying notches in the connected members; and to the latter feature I make claim, not only in the combination wherein it is here shown and described, but also withoutlimitation to its place of use.

I claim:

1. The combination with two pivotally connected parts and a rivet providing the pivot connection between them, of means for limiting the relative rotation between said parts comprising a lug projecting from the side of the rivet and notches in said parts in which the lug is contained, the sides of said notches serving as stops for the lug, and one of the notches being wider than the lug.

2. A container having a cylindrical wall and an end wall or head, a cap surrounding said cylindrical wall and being rotatable relative thereto, said cylindrical wall and cap having lateral ports and central apertures in their heads, said heads having notches therein communicating with said apertures, a rivet passing through the apertures and attaching the cap to the container, and a lug on said rivet extending into said notches and limiting the rotation of said cap.

3. A container having a neck, a cap surrounding said neck and rotatable thereon, said neck and cap having ports in the side walls thereof, and apertured heads at one end, a rivet passing through said heads, notches in the heads communicating with the apertures, and a lug on the rivet extending into said notches, snugly fitting the notch in one of the heads, and adapted to abut against the sides of the notch in the other head to limit rotation of the cap.

4. A container having a neck, a cap surrounding said neck and rotatable thereon, said neck and cap having apertured heads at one end, and ports in the side walls thereof, a rivet passing through said heads, notches in the heads communicating with the apertures, and a lug on the rivet extending into the notches, and snugly fitting the notch in the head of the cap, and adapted to abut against the sides ofthe notch in the head of the neck to limit the rotation of the cap relative to the neck.

A container havinr a neck, a cap surrounding said neck, and rotatably connected therewith, apertures in the sides of said neck and cap, adapted to be brought into coincidence with each other, apertured heads at the outer ends of said cap and neck, and a rivet passing through the apertures in said heads and connecting the cap and neck together; said rivet having a lug projecting to one side, the cap head having a notch in which said lug is confined, and the neck head having a wider notch into which the lug extends and the sides of which form stops complemental to the lug to limit the rotary movement of the cap.

6. A collapsible container for fluid material of pasty consistency, having an end wall and a lateral outlet port, a valve cap embracing that part of the container in which said port is located and having likewise an end wall overlying the first named end wall, and further having a port adapted to be placed, by rotation of the valve, into and out of registry with the first named port, and a rivet passing through said end walls pivotally connecting the valve to the container, the container end wall having a notch and the rivet having a lug occupying said notch to limit rotation of the valve,

and the rivet having also a flange covering said notch.

In testimony whereof I have afiixed my signature.
